For those with an unpatched Switch running Atmosphere or SX OS:
Context assumption: you mean the Nintendo Switch NSP (game file) community release and a new DLC update for Warhammer 40,000: Boltgun. I’ll treat this as a commentary on the update’s design, player impact, and practical steps for players and owners (legitimate purchasers) to get the most from the update.
Conclusion A well-crafted DLC for Boltgun should expand enemy encounters and weapon options while preserving the tight, fast-paced loop and Switch performance. Players benefit most by testing new content in safe runs, using performance presets if available, and following official channels for patches and support.
If you want, I can: a) draft suggested balance numbers for two example weapon mods and two enemy variants, or b) write short player build guides optimized for the DLC—pick one.

The Warhammer 40000: Boltgun Switch NSP is a near-perfect conversion of a modern retro shooter. While it cannot match the 240 FPS of a high-end PC, the ability to slay heretics in bed or on a plane is worth the visual compromises.
With the Forges of Corruption DLC Update, the package transforms from a 7/10 nostalgia trip into a 9/10 essential shooter for the Switch library. The new weapons, enemies, and endless Horde Mode provide hundreds of hours of replayability.
Final Score (with DLC): 9/10
Let’s be direct. The base Boltgun campaign is fantastic, but the final third feels repetitive. The "Forges of Corruption" DLC fixes this.
In the grim darkness of the far future, there is only war. For a long time, Nintendo Switch owners feared that statement translated to "there are only poorly optimized ports." However, Warhammer 40,000: Boltgun shattered those expectations. As a love letter to the retro "Boomer Shooter" era, the game delivers high-octane demon-slaying action that fits surprisingly well into the portable hybrid nature of the Switch.
With the game receiving post-launch support through DLC updates, the discussion around the file structure (often referred to as NSP in the modding and homebrew communities) has become a topic of interest for tech-savvy players.
